ISO 17440:2014旨在与其系列中的其他相关国际标准一起使用。因此，它们规定了防止吊钩危险的一般条件、要求和方法，作为所有类型起重机的一部分。 ISO 17440:2014涵盖了吊钩的以下部分和类型:由钢锻件制成的任何类型的点钩主体；带螺纹/螺母悬挂的机加工钩柄。其原理可应用于其他类型的杆钩，也可用于确定和使用与该杆结构相关的应力集中系数的情况。钢板钩是由轧制钢板的一个或多个平行部件组装而成，不包括在内。 ISO 17440:2014适用于极限强度不超过800 N/mm2且屈服应力不超过600 N/mm2的材料制成的吊钩。 其目的是减少或消除与以下危险相关的风险:超过强度极限（屈服、极限、疲劳）； 超过材料的温度限制；负载意外脱离吊钩。 本标准适用于一般吊钩设计和出版日期后制造的起重机，并作为特定起重机类型产品标准的参考依据。 它只涉及符合ISO 8686-1的极限状态法。

ISO 17440:2014 is intended to be used together with the other relevant International Standards in its series. As such, they specify general conditions, requirements and methods to prevent hazards in hooks as part of all types of cranes. ISO 17440:2014 covers the following parts of hooks and types of hooks: bodies of any type of point hooks made of steel forgings; machined shanks of hooks with a thread/nut suspension. Its principles can be applied to other types of shank hooks and also where stress concentration factors relevant to that shank construction are determined and used. Plate hooks, which are those assembled from one or several parallel parts of rolled steel plates are not covered. ISO 17440:2014 is applicable to hooks from materials with ultimate strength of not more than 800 N/mm2 and yield stress of not more than 600 N/mm2. It is aimed at reducing or eliminating the risks associated with the following hazards: exceeding the limits of strength (yield, ultimate, fatigue); exceeding temperature limits of material; unintentional disengagement of the load from the hook. It is applicable to hook designs in general and to cranes manufactured after the date of its publication, and serves as a reference base for product standards of particular crane types. It deals only with the limit state method in accordance with ISO 8686？1.
